Description

Packed with power to handle the environments of small and medium-sized business NAS and increased workloads for SOHO customers, the WD Red Plus is ideal for archiving and sharing, as well as rebuilding RAID arrays in systems using ZFS and other file systems.

Built and tested for NAS systems with up to 8 bays, these drives offer you the flexibility, versatility, and confidence to store and share your valuable files at home and work.

For small or medium businesses

Stream, back up, share, and organize your digital content with a NAS and WD Red Plus drives designed to effortlessly share content with devices in your home or business. 

NASware technology increases the compatibility of your drives with your existing network and devices. For larger businesses with up to 24 bays, rely on WD Red™ Pro drives that deliver exceptional performance.

Built for optimal NAS compatibility

WD Red Plus drives with NASware technology take the guesswork out of choosing a drive. Optimized for NAS systems, our unique algorithm balances performance and reliability in NAS and RAID environments. 

Simply put, a WD Red Plus drive is one of the most compatible drives available for NAS enclosures. But don't just take our word for it. WD Red™ Plus drives are the result of extensive NAS technology partner engagement and compatibility testing.

WD Red Pro for large businesses

If you are looking for heavy-duty performance for NAS, WD Red Pro NAS hard drives provide exceptional performance for medium and large business customers with extreme demands. 

For NAS environments with 9 to 24 bays, WD Red Pro units deliver uncompromising performance and unwavering confidence backed by a 5-year limited warranty.

3D Active Balance Plus

The improved dual-stage balance control technology significantly enhances the overall performance and reliability of the motor. 

Hard drives that are not properly balanced can cause excessive vibration and noise in a multi-drive system, reduce the lifespan of the hard drive, and degrade performance over time.

24/7 Environment

Given that the NAS system is always operational, a reliable drive is essential. With an MTBF of up to 1 million hours, the WD Red Plus drive is designed to handle 24x7 environments.

Desktop Drives vs. WD Red Plus

Do the right thing for your NAS and choose the drive that is specifically built for NAS with a range of features that help maintain your data and keep optimal performance. Consider the following when choosing a hard drive for your NAS:

  • Compatibility: 3.5" HDDs have been specifically tested for compatibility with NAS systems for optimal performance.
  • Reliability: The always-on environment of a NAS or RAID is hot, and desktop drives are typically not designed and tested under these conditions, unlike WD Red Plus drives.
  • Error recovery controls: WD Red Plus NAS hard drives are specifically designed with RAID error recovery control to help reduce failures in the NAS system.
  • Noise and vibration protection: Desktop drives designed to operate alone usually offer little to no protection from the noise and vibration present in a multi-drive system. WD Red Plus drives are designed to thrive in multi-bay NAS system environments.

    It was purchased in 2019 for use on a desktop. I know that NAS is not meant for desktop use, but it is certainly more durable, so I put it on a desktop that was used very little in these 4 years, a total of 120 days of use, and suddenly, without showing any signs of failure, with 100% health in the program and all checks ok, it gave up the ghost. It's a shame because I've been using WD for so many years, but I think it's starting to break down and I'll probably go for Seagate, as they say it's starting to improve, I'm looking at an Ironwolf.

    Good disk, I got it for a back up disk, it was working about 1-2 times a month, but it failed after 11 months... unfortunately. It was replaced under warranty with the same one... fingers crossed.

    I have had 2 disks connected to my Synology DiskStation DS218J for over 3 months and they have endured over 20 blackouts without any issues. I will immediately install a UPS as a precaution. I am completely satisfied with their durability and performance.

    The product arrived damaged... I sent it back a month ago and still haven't received any notification about what was wrong with it... nor my money back, of course... The response was that they will send it to the company and let me know... for something I didn't even get to use for a minute... UNACCEPTABLE...

    Three were purchased to be used in raid5. No problems appeared, but they only functioned for a month. Speed and noise are as expected for an HDD. They are worth the cost/MB.

    I have him on a NAS only with movies and I bought him solely for reliability reasons so as not to lose 3TB of movies out of the blue, as we say in my village. Let's see if he will last for 5 years since I paid a lot for him.

    4 pieces in the 1st NAS for 2 years, no problem.
    2 pieces in the new NAS for 1.5 years... no problem.

    They have even survived many power outages (pre-UPS) without issue!

    I had purchased a pair in April 2016 but a few days ago (August 2016), one of them failed after displaying an error and ultimately not synchronizing in the NAS's RAID1. I sent it back to WD under warranty and am waiting to hear back from them. I hope they will send me a replacement disk.

    Update1: The disk was replaced by WD without issue and there is no longer a problem. The replacement process through the warranty was quick and effective.

    Update2: September 2019 and they are still functioning in the NAS without any problems.

    The first disk they sent me had a problem, so they replaced it.

    2. The new disk works great so far, with low temperatures (30-31 degrees idle and 38-40 full) and good speeds (125-135mb/s).

    3. I bought it purely for backup and only use it in a case when I need it, so maybe the red was a bit of an overkill for me, but for NAS and servers, the disk is perfect as it is designed for that.

    4. I will monitor how the disk performs in the coming months and will update my evaluation in case something happens.

    5. 4 stars because the first disk had an issue, and depending on how satisfied I am with the disk in the future, I will increase or decrease the rating.

    6. 8/11/18 update: I haven't had any problems with the disk so far, although I use it very little (it's only for backup), so I give it 5 stars and will update if anything happens!

    I have two of them on a NAS and they have been playing without downtime 24/7 for about 4 months now. The NAS runs monthly diagnostics. Neither of them has caused any problems. It's still early to judge, of course. Their speed is satisfactory, as promised. The 4-year warranty gives you peace of mind for a long time after purchasing them. You know they will definitely pay off

    The disk has been in the home NAS for about a year now - it hosts family data (photos, videos, etc.), work files, and backups of laptops, tablets, and phones. It is particularly quiet and does not produce much heat (30-31C, which is 5-6 degrees lower than the older Hitachi in the same case). I can't say anything about speed because the NAS is low-end anyway. The goal is for it not to create problems over time.

    When I bought it, it was the best in terms of features and price. In the future, I plan to replace the old Hitachi with another 6TB WD Red.

    4 pieces in the 1st NAS for 2 years, no problem.
    2 pieces in the new NAS for 1.5 years... no problem.

    They have even survived many power outages (pre-UPS) without issue!

    I had purchased a pair in April 2016 but a few days ago (August 2016), one of them failed after displaying an error and ultimately not synchronizing in the NAS's RAID1. I sent it back to WD under warranty and am waiting to hear back from them. I hope they will send me a replacement disk.

    Update1: The disk was replaced by WD without issue and there is no longer a problem. The replacement process through the warranty was quick and effective.

    Update2: September 2019 and they are still functioning in the NAS without any problems.

    The first disk they sent me had a problem, so they replaced it.

    2. The new disk works great so far, with low temperatures (30-31 degrees idle and 38-40 full) and good speeds (125-135mb/s).

    3. I bought it purely for backup and only use it in a case when I need it, so maybe the red was a bit of an overkill for me, but for NAS and servers, the disk is perfect as it is designed for that.

    4. I will monitor how the disk performs in the coming months and will update my evaluation in case something happens.

    5. 4 stars because the first disk had an issue, and depending on how satisfied I am with the disk in the future, I will increase or decrease the rating.

    6. 8/11/18 update: I haven't had any problems with the disk so far, although I use it very little (it's only for backup), so I give it 5 stars and will update if anything happens!

    I have two of them on a NAS and they have been playing without downtime 24/7 for about 4 months now. The NAS runs monthly diagnostics. Neither of them has caused any problems. It's still early to judge, of course. Their speed is satisfactory, as promised. The 4-year warranty gives you peace of mind for a long time after purchasing them. You know they will definitely pay off

    The disk has been in the home NAS for about a year now - it hosts family data (photos, videos, etc.), work files, and backups of laptops, tablets, and phones. It is particularly quiet and does not produce much heat (30-31C, which is 5-6 degrees lower than the older Hitachi in the same case). I can't say anything about speed because the NAS is low-end anyway. The goal is for it not to create problems over time.

    When I bought it, it was the best in terms of features and price. In the future, I plan to replace the old Hitachi with another 6TB WD Red.

  • Reliable, I have been using it for 2 years as a second disk on a PC that almost never shuts down.

    I got two pieces. One of them started malfunctioning in a few months. I will send it for inspection and update.

    I have 3 on my NAS and they've been working without any issues for the past 2 years. They're fast for HD streaming, don't raise temperatures, and relatively quiet (there are 3 so it's logical to hear them).

  • It was purchased in 2019 for use on a desktop. I know that NAS is not meant for desktop use, but it is certainly more durable, so I put it on a desktop that was used very little in these 4 years, a total of 120 days of use, and suddenly, without showing any signs of failure, with 100% health in the program and all checks ok, it gave up the ghost. It's a shame because I've been using WD for so many years, but I think it's starting to break down and I'll probably go for Seagate, as they say it's starting to improve, I'm looking at an Ironwolf.

  • Good disk, I got it for a back up disk, it was working about 1-2 times a month, but it failed after 11 months... unfortunately. It was replaced under warranty with the same one... fingers crossed.

  • I have had 2 disks connected to my Synology DiskStation DS218J for over 3 months and they have endured over 20 blackouts without any issues. I will immediately install a UPS as a precaution. I am completely satisfied with their durability and performance.

  • A very good "tool", I've had it for 4 months and it's fast and quiet. So far, I'm quite satisfied with its performance although I think the price is a bit steep.

  • The product arrived damaged... I sent it back a month ago and still haven't received any notification about what was wrong with it... nor my money back, of course... The response was that they will send it to the company and let me know... for something I didn't even get to use for a minute... UNACCEPTABLE...
